Volkswagen has announced that authorities have approved its proposed fix for about 8.5 million diesel engines in Europe.

Approval by Germany’s KBA motor transport authority has been granted and will extend across the European Union’s 28 national markets. The fixes apply to the 1.2, 1.6 and 2.0-liter diesel engines, which will all receive a software update that will take about 30 minutes. In addition, the 1.6-liter engine will require the installation of a piece of mesh to regulate air flow, adding about another 30 minutes of labor. Volkswagen is calling the add-on a “flow rectifier” that will be fitted in front of the air mass sensor.

The German automaker will recall the vehicles in waves starting with the 2.0-liter models in the first quarter of 2016. The 1.2-liter engine fixes are scheduled to begin at the end of the second quarter, while the 1.6-liter fix will commence in the third quarter.

Customers affected by the diesel scandal in Europe will be contacted “without delay as soon as the addresses are provided by the KBA,” Volkswagen said in a statement. Rental cars will also be provided free of charge if a customer needs one.

The company reiterated that all vehicles are technically safe to drive and can be used on the road without any restrictions.
